1 Material Safety Data Sheet SKD-2 Date of issue: Date of expiry: JSC «Voronezhsynthezkauchuk» urges the recipient of this Safety Data Sheet to study it carefully to become aware of hazards, if any, of the product involved. In the interest of safety you should (1) notify your employees, agents and contractors of the information on this sheet, (2) furnish a copy to each of your customers for the product, and (3) request your customers to inform their employees and customers as well. 1. IDENTIFICATION OF THE SUBSTANCE/ PREPARATION AND OF THE COMPANY / UNDERTAKING Identification of the substance or preparation Chemical name: Butadiene Synthetic Rubber SKD-2 2. COMPOSITION / INFORMATION ON INGREDIENTS Ingredient % weight Exposure limits Hazards mg/m 3 Butadiene 1, Antioxidant Agidol 1 0,4-1, HAZARDS IDENTIFICATION Main hazards and effects: Rubber SKD is non-dangerous product, according to its influence on the health. Skin contact does not cause any irritation. Does not contain nitrosamines or nitrosamine generated substances. At high temperature or during the processing method, rubber SKD may release the vapor of residual monomer butadiene and hydrocarbon solvent, used at polymerization. In case of fire, the hazard must be identified by the present of carbon oxide. 4. FIRST AID MEASURES Inhalation In case of irritation: milk with mineral water. In case of emergency: remove to fresh air. In case of poisoning: tea, see the doctor Eye contact Immediately flush eyes with water. See the doctor Skin contact Immediately flush skin thoroughly with soap s solution in water. Symptomatic treatment as in case of burns.

2 5. FIRE-FIGHTING MEASURES Extinguishing media Suitable: - fire blanket - foam - powder - carbon dioxide - inert gas ( in case of small fires) - vapor - air-mechanical foam - water with wetting agents - powders ( in case of larger fires) Special fire fighting procedures Maintain the distance from the fire. Use the water for rubber bale s cooling. Special protective equipment for firefighters Use fireproofs clothing. Wear heat resistant clothing, self-contained breathing apparatus. Unusual fire and explosion hazards Rubber is a fire and explosive-proof product. By introduction in fire s source, the formation of fumes may cause the irritation of respiratory tract. Hazardous products are carbon oxide and carbon black. Temperature of self ignition C Temperature of ignition C 6. ACCIDENTAL RELEASE MEASURES Main precaution Maintain the storage, transportation, handling terms. Eliminate sources of ignition. Use the equipment without ignition source. Personal precaution Wear heat resistant clothing, self-contained breathing apparatus. Environmental precautions Use fire-fighting media, anti-fumes systems. Control of hazard ingredients. 7. HANDLING AND STORAGE HANDLING Advice on safe handling Handle only in room with ventilation. Air speed should be 0,5 m/sec. Other precautions Storage terms 1 year. Avoid any contamination and direct sunlight, storage temperature is no more than 30 0 C. Avoid storage with acids, organic solvents and any chemical materials.

3 Rubber, wrapped in polyethylene film and packed on the pallets, is stored in stacks in 3- layers. Rubber, packed in polyethylene film and paper bags, is stored in stacks with height no more than 1,2?. 8. EXPOSURE CONTROL/PERSONAL PROTECTION Exposure limits Ingredient type Value Hazard Butadiene 1,3 100 mg/m 3 4 Toluene 150/50 mg/m 3 3 PERSONAL PROTECTION Hand protection/protective gloves Resistant protective gloves Industrial hygiene measures Do not smoke, eat and drink while working. Remove contaminated clothing and clean it. 9. PHYSICAL AND CHEMICAL PROPERTIES Physical state at 20 0 C: Hard, uniform elastic mass Appearance: Bales of pale color Odor: Absence Density: kg/m 3 Melting temperature: No more than C Degradation temperature: No more than C Self-ignition temperature: 332 0? Organic solvent solubility: Soluble at normal conditions only in organic solvents 10. STABILITY AND REACTIVITY STABILITY Product is stable in normal conditions Conditions causing dangerous changes: Warming, direct sunlight over a long period of time, open fire. Incompatible materials: Concentrated acids, oxidizers, and organic solvents. Another information: Warming, oxygen, ozone, and direct sunlight cause butadiene-styrene rubber s structure changes with decrease of its physical-mechanical properties. 11. TOXICOLOGICAL INFORMATION Acute Toxicity In accordance with significant data with possible relevance, this rubber may be referred as a lowtoxicity product. Rubber processing is characterized as low-toxic. Rubber toxicity is caused by the

4 possible respiration of butadiene and toluene vapor in amounts significantly lower as exposure limit during rubber processing and warming. DL mg/kg, rats?l 50 not obtained Inhalation hazards: Non-dangerous product at processing and handling. Skin contact: Does not cause irritation with skin contact. At the same time it is recommended to keep precaution measures as outlined in sections 7 and 8 of this document. Main effects as a result of short time and long-time influence: There isn t information on the hazards and influence of butadiene-styrene rubber if all safety measures are kept. Information about influence of some product ingredients on human body: Butadiene Lim IR 3,6 mg/m 3 CL mg/m 3 at 7 hours exposure for human being Embriothropic, gonadothropic, mutagene, sensibilizing effects of butadiene was determined. Toluene DL mg/kg, injection, rats DL mg/kg, injection, mouse CL mg/m 3 at 4 hours exposure for rats Lim IR 150 mg/m 3, human being Embriothropic, gonadothropic, mutagene, sensibilizing effects of toluene was determined. 12. ECOLOGICAL INFORMATION Possible environment relevance: The rubber properties do not change under the conditions of environmental influence. The product has poor biodegradable characteristics. Ground and water contamination may take place as a result of incorrect rubber waste disposal and air contamination as a result of incorrect waste incineration. The most influential properties of substance on environment: Hygienic norms: For rubbers are not determined; for residual monomer butadiene and solvent Butadiene Toluene Air in populated areas: Exposure limits 3 mg/m 3 0,6 Exposure limits 1 0,6 Hazards 4 3 Water Exposure limits 0,05 0,5 Hazards 4 4

5 Fish Exposure limits - 0,5 Hazards - 3 Ground Exposure limits - 0,3 13. UTILIZATION AND DISPOSAL CONSIDERATIONS Safety measures on wastes handling formed during processing, storage, transportation etc. Rubber waste treatment, suitable for further use must be done in rooms, supplied with suction and exhaust ventilation. Specific safety measures are not required.
